Abstract: 496,285. Coin-freed liquid delivery apparatus. BEER, T. Feb. 25, 1937, Nos. 5682, 5683, and 5684. Void. Convention dates, Feb. 25, 1936, Aug. 19, 1936, and Nov. 6, 1936. [Classes 27 and 106 (v)] A coin-freed apparatus for dispensing bottled beverages directly from the bottle comprises a vertical casing 10 housing the coin-freed operating mechanism, and an attached horizontal casing 30 housing a suction bellows 31 and forming a support for the bottle. A measuring and dispensing device 66 insertable into the neck of the bottle, is connected with the bellows 31 by tubing 61 having a telescopic adjustment at 4 to provide for the accommodation of different sized bottles. Depression of a plunger 12 after insertion of the requisite coins operates through a bell-crank 35 to compress the bellows 31, the air being discharged, first through a vent 40, and subsequently, when the vent has been closed by an adjustable valve 41 carried by an arm of the bell-crank 35, through an exhaust valve 44. During the return stroke of the plunger 12 and bellows 31 under the action of springs 24 and 37, suction is applied by way of the tube 61 to an upper measuring chamber 69 of the device 66, and liquid is drawn by way of a tube 74 from the bottle into the measuring chamber, rising to a level above the top of the tube. When the valve 40 reopens towards the end of the return stroke of the plunger 12, the suction of the bellows is released, and surplus liquid in the measuring chamber 69 above the top of the tube 74 runs back into the bottle, the capacity of the chamber 69 below the level of the top of the tube thus determining the volume delivered. To release the liquid in the chamber 69, a plunger 86 is depressed. An upper piston 83 on this plunger opens a vent 94 in the chamber to the atmosphere, and a lower piston 84 allows the liquid to flow out through a vent 95 and a spout 93. When the plunger 86 returns, surplus liquid in the spout runs back down its sloping lower wall into the space 97, and thence through openings 98 and 72 into the bottle. Baffles 76 and 77 prevent liquid being drawn into the tube 61 during the suction stroke. Coin action, multiple coin.-Depression of the plunger 12 is normally prevented by engagement of a spring-actuated catch lever 14 with the upper end of an elongated cavity 13 in the side of the plunger. Several coins must be inserted to free the mechanism, the coins piling one above the other in the cavity 13, and the uppermost releasing the catch lever 14 to permit operation. Coin-slit closing-devices.-At each operation of the apparatus, a pawl 62 on the plunger 12 advances a ratchet wheel 51 whose initial position is adjusted according to the capacity of the bottle. After a number of operations sufficient to empty .the bottle, a pin on the ratchet wheel operates a lever 57 to close the coin slot and prevent insertion of further coins. A clock mechanism may also be provided to close the coin slot during certain hours of the day, and running down of the clock mechanism may also close the coin slot. Delivery of articles stored in piles.-Drinking cups are stored in a nested stack 110 in a casing attached to a wall of the apparatus. A sliding carriage 118 connected with the plunger 12 supports the stack, and in its normal uppermost position, Fig. 9, a pawl 125 pivoted thereon engages under the rim of the penultimate cup. Upon depression of the plunger 12 and with it the carriage 118, the support of the penultimate cup is taken over by a pair of levers 116 carried by fixed pivots 116<1>, and the lowermost cup is conveyed to a delivery opening 113 by the carriage. The pawl 125 is operated by a pin 124 thereon working in a fixed cam track 128, and the levers 116 by engagement of their curved edges with the pin 124.
